Drill Results

Leviathan Gold, via Core Prospecting Pty Ltd. Receives High Grade Assay Results, from

Initial Phase of Diamond Drilling at the Excelsior Prospect.

• Highlights include 4.85 meters at 9.0 g/t Au (43.66 gram meters) in hole EH014, 3.13

meters at 56.9 g/t Au (178.23 gram meters), in hole EH017 and 12.68 meters at 9.2 g/t

Au, (116.85 gram meters), in hole EH029.

• A total of 1964.65 meters of diamond drilling over 16 holes has been completed by

Core Prospecting Pty Ltd.

• Drilling identifies mineralized dilational zone open ing to the northeast , remain ing

open along strike and depth.

Vancouver, BC – June 25, 2024 - Leviathan Gold Ltd. (“ Leviathan”, the “Company”) (LVX –

TSXV, 0GP – Germany) is pleased to announce receipt of full assay results from an initial phase

of diamond drilling completed at its Excelsior Prospect ( “Excelsior”) pursuant to a Heads of

Agreement entered into between Leviathan and Core Prospecting Pty Ltd (“ Core”) on July 17,

2023 as subsequently amended on January 16, 2023 (“ HOA”). The most prominent intervals

among these results are presented in Table 1, and include 4.85 meters at 9.0 g/t Au (43.66 gram

meters) in hole EH014, 3.13 meters at 56.9 g/t Au (178.23 gram meters), in hole EH017 and 12.68

meters at 9.2 g/t Au, (116.85 gram meters), in hole EH029. Additional drilling will be required to

determine the true thickness of mineralization. Further pursuant to the HOA, Leviathan has

received notification from Core of its intention to commence a second phase of diamond drilling

at Excelsior. Accordingly, as a result of Core completing the initial phase of diamond drilling it

has earned a 40% interest in in a New Tenement to be applied for by Leviathan, subject to the

fulfilment of certain further conditions by Core.

A total of 1964.85 meters of diamond drilling over 16 holes has now been completed by Core in a

series of generally parallel south-eastward and north-westward oriented fans of drill holes designed

to test for continuations of known mineralization (Figure 1).

The purpose of the Core program was to drill beneath and along-structure from intervals previously

reported by Leviathan from Excelsior, which include 8.24 g/t Au over 6.63 meters (54.63 gram

meters), from 161.95 meters in hole EH003 (press release of April 21, 2021) and 5.40 g/t Au over

11.02 meters (59.51 gram meter s), from 84.37 meters in hole EH005 (press release of April 26,

2021). These intervals are believed to represent the down- dip continuation of mineralization

- 2 -

observed in historic mine workings, and are characterized by intense quartz veining, visible gold,

and enveloping sericitic alteration and base metal sulphides.

Interpretative work on drilling completed to date suggests the presence of a north -eastward

plunging mineralized dilational zone consisting of quartz reef and associated splays in which gold

is hosted in quartz veins. It may be inferred from the results of drilling, most particularly from hole

EH029 that this dilational zone opens to the northeast, in which regard it remains open along strike

and depth. This feature will be the subject of further drill-testing.

Highlights of results to date are provided in Table 1, collar information in Table 2, and full results

in Table 3.

Excelsior lies within the Company’s Avoca Project in the Victorian Goldfields, Australia . As a

preliminary component of the HOA Core, a private small -scale mining contractor based in

Bendigo, earned an initial 40% interest in a New Tenement covering a three-square kilometre area

within EL5387 to be applied for by Leviathan by completing, at its sole cost, 2,000 meters of

- 2 -

diamond drilling including assays by April 17, 2024, subject to the fulfilment of certain further

conditions by Core.

Leviathan Gold Chief Executive Officer, Luke Norman, remarked: “We are delighted by the

success of Core Prospecting’s Phase 1 program at Excelsior, and the potential for depth and strike

extensions to known high-grade mineralization returned by our own drilling that this now reveals.

This campaign provides Leviathan with the oppor tunity to define a high-grade gold deposit of

significance, of particular interest and relevance given the recent success of others in Victorian

gold exploration. We thank Core for their considerable efforts to date and look forward to working

with their highly skilled team as this program continues to evolve.

About the HOA

Under the terms of the HOA, Core may earn an initial 40% interest in a three square kilometre

area within EL5387 (the Excelsior Area of Interest, or “AOI”) by completing, at Core’s sole cost

and expense, 2,000 mete rs of diamond drilling including assays by April 17, 2024 (“Phase 1”),

and a further 35% interest in the AOI for an additional 4,000 meters of diamond drilling including

assays and preparing an independent JORC report (the “JORC Report”) identifying an Indicated

and/or Measured Mineral Resource within 12 months from the end of Phase 1, each at Core’s sole

cost and expense (“ Phase 2 ”). In lieu of completing such further drilling, Core may instead

prepare, at its sole cost and expense, a JORC report containing Indicated and/or Measured Mineral

Resources of not less than 50,000 ounces of gold at a cut -off grade of 2.5g/t Au within the AOI.

Upon fulfilment of certain conditions by Core, Leviathan shall on behalf of Core apply for a

standalone tenure over the AOI, (the “ New Tenement”). If Core fails to complete Phase 2 they

shall forfeit any interest under Phase 1 and shall have no interest in the AOI.

Upon Core having attained a 75% equity interest in the AOI, Leviathan may either contribute its

share of costs and maintain its equity interest or be diluted pro-rata to a minimum carried interest

of 5%, which Core shall purchase from Leviathan for the sum of AUD$150 per ounce of Indicated

and/or Measured Mineral Resource s as estimated in the JORC Report, payable upon

commencement of gold production. Alternatively, Core may, within 12 months of the completion

of Phase 2, purchase Leviathan’s holding in the AOI for the sum of AUD$75 per ounce of Indicated

and/or Measured Mineral Resources in the JORC Report, or Core may within 12 months of the

completion of Phase 2 purchase Leviathan’s holding in the Excelsior AOI by paying instalments

of AUD$25,000 per quarter, increasing to AUD$75,000 per quarter, commencing from the date

on which a New Tenement is granted and continuing for the life of any gold production mine

located within the area of the AOI.

The HOA also provides that Leviathan may , subject to Core first completing Phase 1, claw back

Core’s equity stake in the AOI for the sum of AUD$500 per meter drilled, or after receipt of the

JORC Report for AUD$150 per ounce of gold mineralisation estimated and classified as an

Indicated Mineral Resource and/or a Measured Mineral Resource in the JORC Report.

About the Excelsior Prospect

The Excelsior prospect is interpreted to host structurally controlled gold mineralization developed

within quartz veins. Historic production records from Excelsior indicate the mining of 13,200 tons

for 9,260 ounces of gold down an ore shoot to a depth of 100 meters at an average recovered grade

of 22 g/t Au between 1909 and 19151, with said mineralization open to depth and along strike . A

total of 1,917 meters in 11 holes have been drilled at Excelsior by Leviathan to date.

Qualified Person and Data Verification

The technical content of this news release has been reviewed, verified and approved by Keith

Whitehouse, MAusIMM (CP Geol), MAICD, Exploration Manager of Leviathan Gold (Australia)

Pty. Ltd., a qualified person as defined by NI 43-101.

Drilling was carried out by Core using their equipment, and all core was drilled at NQ size.

Average core recovery for the program was 96.6%. Drill core was cut in half by Core using a

diamond saw, with one half of the core then taken as a sample for analysis. Samples were sawn

along the bottom of hole orientation line, or if none present a consistent cutline as marked by the

logging geologist. Sample intervals were generally between 10 and 150 centimetres , producing

samples of between 0.27 to 4.0 kg. Sampl es were delivered to On Site Laboratory Services (Pty)

Ltd (“ On Site ”), in Bendigo, Victoria. The samples were coarse crushed to P80 <2mm using

industry standard Boyd crushers with a 1kg sub-sample being packed into standard containers for

assay using a Chrysos Corporation Photon Assay analyser, lab method code PAAU02. Regular

crush duplicates were generated and reported by the laboratory together with regular replicate

results of the primary sample. Replicate results were provided for 100% of gold grades greater

than 10 g/t and more than 85% of grades greater than 5 g/t. Core routinely inserted Photon Assay

certified geochemical standards and blanks together with samples flagged for coarse crush

duplicate-sampling into the drill core sample stream as part of a documented Quality

Assurance/Quality Control ( “QAQC”) process to monitor laboratory performance. During the

drilling program QAQC material was inserted into every sample batch at the following average

rates per primary sample: crush duplicates 1 in 30; basalt blanks 1 in 30; certified reference

material 1 in 30. QAQC sampling was considered to provide acceptable results. Sample grades

were checked against recovery percentage for potential bias; no discernible high- or low-grade

bias was observed.
